I've been using CH Combatstick, pedals and throttle for many years, very satisfied with them.
For Aces High there are enough buttons (I do not use buttons for landing gear, tail hook, bailout, etc), only for flight controls, views, guns, flaps and dive brakes. When playing around with X-plane I find I could use more buttons for some of the other functions such as thrust vectoring, wing-sweep, etc.
